The entire global atmosphere has been polluted by the aerosol spray operations. So much so that the change is clearly visible in recent sat images. The earth is enveloped in a haze. It is also noteworthy that global warming has accelerated. Of course no mention of chemtrails is ever made officially in respect to global warming. However it is obvious from sat photos that the trillions and trillions of nano sized metal particulates have created a hazy blanket surrounding the globe. These particulates act to reflect back warmth & energy that would normally dissipitate into outer space.
